{1310. 557,614. Patented Apr. '7, 1896.

UNITED STATES PATENT ()FFICE.

JOHN SIGMUND SCIIMITT, OF NEV YORK, N. Y.

INVALID-BED.

SPECIFICATION forming part of Letters Patent No. 557,614, dated April 7,1896.

Application filed January 3, 1896.

To all whont it nmy concern.-

Be it known that 1, Jon): Srennxn ScHinTr, a citizen of the UnitedStates, residing in New York, in the county and State of New York, haveinvented certain new and useful Improvements in Invalid-Beds, of whichthe following is a specification.

My invention relates to beds and chairs; and it consists of an invalidbed or chair for invalids use from which a portion of the mattress (orcushion) can be removed by a lever combination arranged on anoscillating shaft and at the same time a vessel or receptacle for theexcretion of the invalid lifted in the opening thus created.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of a bed, a part thereof being shown in section todisclose the arrangement of the parts comprising my invention. Fig. 2 isan enlarged sectional view showing details of construction. Fig. 3 is anenlarged cross-section on the line 3, indicated in Fig. 1. Fig. at is asectional elevation showing the modified construction of my invention asadapted to an invalids chair.

Similar letters of reference in all the views indicate correspondingparts.

The mattress 13 in my improved invalid-bed has in the place wherenormally the lower end of the body will lie a hole I) about eighteeninches square. The hole is lined with waterproof material, and on thesides are fastened segmentally-curved rails 6, extending downward towardthe foot of the bed to the cross-piece a, to which their ends aresecured. The sides of the hole Z) toward the ends of the bed arecorrespondingly arcuated to admit the spherical motion of the bowl 0 andto allow the sliding cushion C to pass along on the rails in and out ofits place in the mattress.

Sliding cushion C is fastened to plate (Z, gliding in rails e andconnected by chains f g to levers h, rigidly secured to shaft 1. Plate(Z is made, preferably, of spring-steel an d curved on the same radiusas the rails e.

To the same shaft I are also rigidly secured the lifting-levers 7:,provided with hooks Z at their ends, holding the trunnions m of ring 12,supporting bowl 0. These levers are so placed in relation to levers 71that when the sliding Serial No. 574,257. (No model.)

cushion C is in its place, filling the hole in the mattress, thereceptacle 0 will be in its lowest position, and again when cushion C ispushed out of its place in the mattress and the hole opened the bowl 0will be moved in its place and elevated to the level of the mattress.

The shaft I is pillowed in bearings secured to the frame of the bedsteadA, and to its squared ends is fitted removable operatinghandle 1),conveniently long and adapted to be, when set on the shaft, in asuitable position within reach of the patient, and as all parts of theapparatus are made to move with greatest ease he may effect the changein the apparatus himself. Mattress B is fastened to the bedstead A toinsure a smooth working of the apparatus, because when the shaftisturned the levers tend to move the mattress on the bedstead.

In Fig. 4 I have shown a modified construction of my above-describeddevice adapted for invalid-chairs. In this instance the rails r are benton the arc of the circle having the shaft for its center, and the bottom3 of the removable cushion t is also bent on the same circle. This isnecessary because a chair is, in proportion to its length, much higherthan the bed, and therefore if a flatter are were used the cushion, whenremoved from its place, would necessarily project in the rear of thechair. The chains f and g are in this case not needed and levers h areattached directly to the plate s. In all other respects the constructionis the same in its general features as the above-described bed.

I claim and desire to secure by Letters Patent- An invalid-bed,comprising a bedstead, a mattress,secured thereon and having an openingin the place where the lower end of the body of the invalid normallylies, curved rails, secured to the sides of said opening, and extendingdownward toward the foot of the bed, a sliding cushion, adapted to fillthe opening in the mattress, a curved plate, secured to the slidingcushion and adapted to slide in the rails; an oscillating shaft,pillowed in hearings in the bed-frame, levers, rigidly secured to saidshaft, chains connect ing the levers to the plate, carrying the slidingcushion; hooked levers, also rigidly secured to said shaft and adaptedto carry a redescribed in the foregoing specification I have eeptacleinto the opening in the mattress, signed myna-me in the presence of twosub- When the sliding cushion is removed therescribing witnesses.
